Python has no pre/post increment/decrement operator. For instance, ``x{plus}{plus}`` and ``++x--++`` will fail to parse. More importantly, ``{plus}{plus}x`` and ``++--x++`` will do nothing. To increment a number, simply write ``++x += 1++``. == Noncompliant Code Example ---- ++x # Noncompliant ---- == Compliant Solution ---- x += 1 ----
